Withings ScanWatch 2 review

Withings ScanWatch 2 is a different kind of smartwatch: an analog watch face with a small display, built for health tracking rather than apps. Withings' US store lists it at $369.95 in 38mm and 42mm sizes, and most listed colors are marked HSA/FSA eligible. Battery is the headline at up to 35 days, the longest on this list, with fast-charging in 2 hours. Resting a finger on the metal bezel records a single-lead ECG in 30 seconds, and the watch also tracks blood oxygen levels, overnight heart rate variability, REM sleep and 24/7 temperature with variation notifications and cycle tracking. It is iOS and Android compatible and shows incoming calls and app notifications. The trade-off is that you do not get an app store, voice assistant or large touchscreen, which is why its feature score sits last. We compared documented features and published prices only.
